Importance and role
Importance of genus to ecosystem
Species of Rhizosphaera are pathogenic and is the causal agent of needle blight of spruce or Picea pungens though it has wide host range such as carious conifers and pines.
Industrial relevance and applications
There are currently no industrial applications of Rhizosphaera.
Quarantine significance
No biocontrol agent has been reported from Rhizosphaera.
Biochemical importance of the genus, chemical diversity or applications
The chemical diversity of Rhizosphaera is unknown. Further studies are needed.
Diversity of the genus
Rhizosphaera comprises eight species known on several hosts but one plant family namely Pinaceae. Rhizosphaera seems to be host specific. Rhizosphaera is reported from several countries such as Europe (Russia, Austria, France, Germany, Czechoslovakia, Norway, Britain, Ireland, Netherland), North America (United States, Canada), Asia (Japan).
